Leading an inactive lifestyle can increase a person’s risk of poluution related asthma according to scientists in the USA.
The scientists found that, after being exposed to ozone the inactive tests shouwed inflammation in the lungs – a symptom of asthma. Exposure to ozone impacted on the breathing rate of both groups.
Ground-level ozone is a type of pollution created by chemical reactions between the sun’s rays and organic gases and oxides of nitrogen emitted by cars, power plants, industrial boilers, refineries, chemical plants and other sources.
The researchers argue that this finding could also be similar among humans, but further research is needed.
